# Specify information about a revision stored in an Amazon S3 bucket
<a name="deployments-create-console-s3"></a>

If you are following the steps in [Create an EC2/On-Premises Compute Platform deployment (console)](deployments-create-console.md), follow these steps to add details about an application revision stored in an Amazon S3 bucket.

1. Copy your revision's Amazon S3 link into **Revision location**. To find the link value:

   1. In a separate browser tab:

      Sign in to the AWS Management Console and open the Amazon S3 console at [https://console.aws.amazon.com/s3/](https://console.aws.amazon.com/s3/).

      Browse to and choose your revision.

   1. If the **Properties** pane is not visible, choose the **Properties** button.

   1. In the **Properties** pane, copy the value of the **Link** field into the **Revision location** box in the CodeDeploy console.

   To specify an ETag (a file checksum) as part of the revision location:
   + If the **Link** field value ends in **?versionId={{versionId}}**, add **&etag=** and the ETag to the end of the **Link** field value.
   + If the **Link** field value does not specify a version ID, add **?etag=** and the ETag to the end of the **Link** field value.
**Note**  
Although it's not as easy as copying the value of the **Link** field, you can also type the revision location in one of the following formats:  
**s3://{{bucket-name}}/{{folders}}/{{objectName}}**  
**s3://{{bucket-name}}/{{folders}}/{{objectName}}?versionId={{versionId}}**  
**s3://{{bucket-name}}/{{folders}}/{{objectName}}?etag={{etag}}**  
**s3://{{bucket-name}}/{{folders}}/{{objectName}}?versionId={{versionId}}&etag={{etag}}**  
**{{bucket-name}}.s3.amazonaws.com/{{folders}}/{{objectName}}**

1. If a message appears in the **File type** list that says the file type could not be detected, choose the revision's file type. Otherwise, accept the detected file type.
